-ffast-math? I have been too paranoid to use it.
-ffast-mathdoes stuff like use CPU instructions for e.g. square roots, rather than calling the math library. I'm less sure how to handle that.
Hi quick question if that's okay, I'm trying out integration with gloss to display a texture generated by accelerate. As a minimal example I tried the following
genPicture :: Array DIM2 Word32 genPicture = fromList (Z:.640:.480) $ repeat 255
but the resulting window remains the same as the background color as if the picture is invisible
